VEHICLE HUB AND SPHNDLE.

SPECIFICATION forming part of Letters Patent No. '713,7 52, datedNovember 18, 1902. Application filed April 8,1902. qcrial No. 101,875.(No model.)

T0 all 107110717. t may concern.'

Beit known that I, LUCIAN D. CRANDALL, a citizen of the United States,residing at Springville, county of Utah, and State of Utah, haveinvented certain new and useful Improvements in Vehicle Hubs andSpindles, of which the following is a specification.

My invention relates to vehicle hubs and spindles.

The object of the present invention is the provision of an improved andnovel axle or spindle box for vehicle-hubs and an-im proved spindlewhich will provide for adjustment for wear, minimize wear and frictionof the parts, exclude dust, and lubricate or oil the parts.

Having the foregoing object in View, the invention consists of certainimproved features and novel combinations, arrangements, and adaptationsof parts set forth in detail hereinafter.

In the accompanying drawings, Figure 1 is a longitudinal section; Fig.2, a longitudinal section with certain parts in full lines, showing theuse of roller-bearings; Fig. 3, a sectional view of a modified form oflubricantfeeder, and Fig. 4 a Sectional detail showing a modifiedconnection for securing the cap to the sand-band.

The numeral 1 designates the hub, and 2 is the boxing, which is providedwith ears or flanges 3, engaging with the hub to prevent the boxing fromturning therein. The boxing has a tapered diameter and is screwthreadedat one end 4, over which screws an externally-screw-threaded collar orsleeve 5, over which screws the dust-cap 6, which is preferably filledwith cotton or waste 7, while 8 is a shell secured on the hub andinclosing the cap.

The numeral 9 designates the axle, which has the tapered spindle 10, and11 is a nut 0r bur screwed onto the end of the spindle and provided witha flange 12, adapted to abut the collar 5 and hold the hub on thespindle.

The numeral 13 is a cone held on the square portion of the axle andabutting the inner end of the hub. On the inner end of the hub is a sandband 14, provided with screwthreads 15.

The numeral 16 designates a cap adapted to screw on the threads 15, andthe cone has a bearing on this cap at 17. The cap is filled with wasteor cotton 16'. As shown in Fig. 4, in place of the screw-threadedconnection between the sand-band 14 and the cap 16 the spring-catch 1Scan be employed, preferably two or three of these catches being used,and they are provided with the pins 19, adapted to project throughopenings in the cap 16 and sand-band 14.

The oiling device consists of a tube 2O in the hub, which feeds thelubricant through an elongated opening vin the boxing and the cap 21,having the plunger 22, which fits said tube 20. This plunger holds thelubricant down on the spindle after a suitable quantity has beenintroduced and prevents the lubricant from moving about or chucking upinto the tube and insures the proper feeding to the spindle.

As shown in Fig. 3, I sometimes prefer to employ alubricant-reservoir23, which screws onto the tube 20. In thisconstruction a plunger-rod 24 is employed, having a swab 25 and athreaded cap 26. The cap 26 is intended to be screwed onto the neck 27of the reservoir, which holds the swab down in the tube 20. The swab isfirst introduced into the tube, the lubricant introduced into thereservoir, and the swab then pushed down into the tube to the spindleand the cap 26 screwed onto the part 27. To supply lubricant to thespindle, the cap 26 is unscrewed and the swab lifted out of the tube andthe tube allowed .to fill with lubricant, after which the swab isreintroduced into the tube and the cap screwed down. The reservoir canbe secured to the spokes ofthe wheels by a suitable clasp and willprovide a means for keeping the spindle properly lubricated at alltimes.

I have adapted roller-bearings to the invention, as shown in Fig. 2.There the boxing is made in two parts, 28 and 29, screwthreaded togetherat 30, and the section of boxing 29 is provided with fianges 31, whichengage the hub to hold the section securely after it has been put inthehub by pressure. The numerals 32 designate the rollers in theboxing-section 29, which are held against longitudinal displacement bythe collar of the cone and by the shoulder 33 on the boxing, while therollers 34, located in the boxing-section 2S, are held againstlongitudinal displacement by the nut or cap on the end of the spindleand inner end of the boxing-s pindle 29.

It will be seen that dust or foreign material cannot gain access to thespindle to clog the same, and when the boxing is Worn out at its endsfrom continued use the cone can be removed and reduced in size to permitthe nut 11 to be screwed up farther' to compensate for the wear.

I am aware that many changes of construction could be resorted to incarrying out my invention, and I do not, therefore, limit myself to theprecise construction herein shown and described, but consider that I amentitled to all such variations as fall Within the spirit and scope ofthe invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In-a device of the class described, the combination with a hub and aboxing therefor, of a spindle passing through the boxing, means forpreventing displacement of the hub and boxing from the spindle, a coneon the spindle, and a cap on the hub which bears against the cone.

2. In a device of the class described, the combination With a hub and aboxing therefor, of aspindle passing through the boxing, means forpreventing displacement of the' hub and boxing from the spindle, a coneon the spindle which has a flange or collar bearing against the boxing,and a cap on the hub which bears against the cone.

3. In a device of the class described, the combination With a hub and aboxing having a screwfthreaded end, of a collar threaded onto saidscrew-threaded end of the boxing, a spindle, a nut threaded onto the endof the spindle and bearing against the end of the boxing and collaraforesaid, and a member.

on the spindle adapted to bear against/the other end of the boxing.

4. In a device of the class described, the combination With a hub and aboxing having a screw-threaded end, of a cap threaded onto saidscrew-threaded end, a spindle extending through the boxing, a nut or capthreaded onto the end of the spindle and adapted to bear against the endof the boxing and 1ocated Within the cap aforesaid, a cone on thespindle having a flange adapted to bear against the opposite end of theboxing, and a cap engaged with the hub and having a bearing on the cone.

In testimony whereof I hereunto affix my signature in presence of tWoWitnesses.
